The agricultural system that produces spectacular yield by eliminating diversity — and the template for understanding what happens when optimization for a single metric degrades the conditions that metric depends on.
A corn monoculture is the most productive agricultural system ever devised, measured by the metric it was designed to maximize: bushels per acre. The yield is miraculous. The miracle has a cost the metric does not capture. The prairie the corn replaced contained four hundred species whose root systems penetrated six feet into the earth, building soil structure that held moisture through drought and drained excess through flood. The diversity of flowering times sustained pollinator populations across the entire growing season. The whole system was a machine for converting sunlight into biological complexity while maintaining the conditions that made the conversion possible. The monoculture does one thing. It produces corn. It degrades every other function the prairie performed.

The distinction between optimization and resilience is the distinction between the monoculture and the prairie. An optimized system maximizes a single metric under expected conditions. A resilient system maintains adequate performance across a range of conditions, including conditions the optimizing system
